PLAYING BALL.

je @ZZ 'zc/7mm t 71mg/ concern:

Be it knewn that L MARCIA C. HAMnLn'r, a citizen of the United States, and a resident of fil-iron, county of Summit, State of Ohio, have invented certain new and useful lin-- pnivements in Playing Balls, of which the folio fing is a specification.

rlhis invention relates to playing balls and particularly to rubber or elastic balls having means formed thereon whereby an elastic cord may be attached to the ball so as to form a return ball. Heretofore, the various means nsed for attaching` the cord to the ball have not proven satisfactory, as no way has been devised to fasten the cord securely to the ball, and in usual constructions the cord has pulled out of the ball after brief use.

rllhe object of the present invention is to construct a new form of playing ball which shall have securely fastened thereon, means by which the return cord can be attached. lt is also an object of the invention to provide such an attaching means from which the cord can be removed without injury to the ball and the ball used as an ordinary playing ball without the return attachment.

In the drawings and description, thereA is shown one form of the invention, but it will be understood that the invention is not necessarily limited to the exact form as shown and described, but may be modified within the scope of the appended claims.

in the drawings:

Figure l is a view of the ball, looking at the attaching means from the side;

Figure 2 is a View looking down upon the attaching means; and

Figure 3 is a section through the ball at the attaching means on the line 3-3 of Figure 2.

rlie ball is made in the usual way, with the two hemispheres connected along the center line where the mold separates. The attaching means is of strong, flexible, substantially ineXtensible material and in the preferred form, is a short piece of string l0, the ends of which are vulcanized within the wall of the ball and provided with a central loop l1 which projects outwardly of the ball and to which the elastic cord 12 may be attached. If it is desired to use the hall in play wit-hout the cord, this can be done and the 'cord can later be attached. 'ihe ball may thus be made to serve a double purpose, which is not possible with former constructions.

ihe' loop or retaining means may be secured to the ball in any suitable manner. lt is an important feature of the invention, however, that it be vulcanized to the ball and ,thereby securely fastened in position.

in vulcanizing the string in position, one ond of the string is placed on each hemisphere and over the ends of the string are placed small patches of rubber 18. rihe loop projects into a cavity formed in onehalf of the mold. The ball is then cured as iu the usual practise.

llfhile l have particularly describedI the retaining member as a string, it is not my lesire to be restricted to a string, as other attaching means may be used if desired. Other methods may be devised for vulcanizing the attaching means in place and the method described may be modified as desired.

The construction which has been shown can be readily manufactured at very slight expense over that required to manufacture the ball without it. The attaching means is securely vulcanized in place and cannot pull out. Other advantages have been described and will be apparent to those skilled in the art.

In addition to those features which have been described, it will be observed that the attaching means does not destroy the balance or contour of the ball and its resiliency and liveliness is retained. This is a considerable advantage over prior constructions in which the surface of the ball has been pierced or ball.

2. in elastic playing ball having ineans whereby a return cord inay be attached, said attaching nieans comprising a flexible elenient the ends oi which are embedded within the wall ot the ball and having,` a central loop projecting outwardly troni the surface oit the ball.

3. in elastic playing ball having a string embedded within the wall ot the ball and projecting outwardly troni the surface thereof to provide means by which a return cord inay be attached.

i. A rubber playing ball and an elastic (ord, in combination with a tiexible eleinent vulcanized within the ball and having a portion projeetiiigl outwardly therefrom to provide an at-taehinp-tgr` ineans for the cord.

i pla'ing bali and an elastic cord, in combination with a string permanently secured to the ball and having av portion projecting outwardly therefrom-to provide attaching ineans for the cord.

(i. A rubber playing ball and an elastic core, in combination with a. string, the ends ot which are vulcanized within the wall ot' the ball and the central portion of which is terme-.fl as a loop projecting outwardly of the surface oi the ball.

A. hollow resilient playing)l ball ot' rubber and a return cord attaching n'ieans permanently secured within the wall ot' the ball and projecting outwardly therefrom.

8. A hollow resilient playing` ball of rubber and a return eord attaching ineans Coniprising a string pern'ianently secured to the wall ot' the ball and having' a loop projecting outwardly therefrom.

A hollow resilient playingl ball of rubber and a return cord attaching` nieans coniprising' a string the ends of which are Vulcanized within the wall ot' the ball and the central portion ot which projects outwardly ot the ball to torni a loop.
